Scotts Pure Organic Premium Seaweed Plant Food

One of the easiest ways to give your plants a nourishing drink that’s filled with nothing but pure organic goodness. Not all seaweed products are the same - many popular brands contain little or no real fertiliser - but your garden will flourish with our certified 100% Scotts Pure Organic Seaweed Plant Food that's enriched with natural nutrients. You're not only feeding your plants but the soil too. It's organic - and it works!

  • Nutrient-rich smart liquid that releases fertiliser over 4-6 weeks
  • Feeds plants and the soil
  • Reduces plant stress caused by drought, frost, disease and pests
  • Rejuvenates the soil - naturally
  • Low odour formulation
  • Easy to apply with Scotts Easy Sprayer - no drips, no hassles and simple On/Off tap on the handle grip
  • Also available as a Concentrate for watering can application

Steady, even feeding

Unlike most liquid fertilisers that give one instantaneous 'hit' of food to plants immediately after application, this formulation releases nutrients over 4-6 week period

Ideal for all plants

Premium 100% organic plant food that contains a blend of natural and organic ingredients to stimulate strong, healthy plant growth; gives your plants all-season vitality and protection

Pure organic

Registered with Australian Certified Organic as a 100% organic plant food

Environment friendly

Encourages earthworms and beneficial soil microbes, creating healthy growing conditions


All ingredients in this plant food come from sustainable and renewable sources

Boosted nitrogen, low pH

Contains 2x the plant-available nitrogen compared to chicken manure alone; also has low pH and phosphorus so it's suitable for natives

Natural nutrients

Includes seaweed, fish meal and organic compounds like humic acids - all in a low odour formulation

Hose-on or Concentrate


The 1L Easy Sprayer bottle is perfect for small gardens, quick fertilising tasks and covers up to 100m2

The 1L Concentrate is the better option for large or difficult to reach areas where a watering can or pump sprayer may be easier to use. It makes up to 300L

Handy Tip: To determine the size of your garden, multiply the length x width in metres. 1 long stride = approx. 1 metre

Suitable for

All trees and shrubs including natives and other phosphorus-sensitive plants

All flowering and leafy annuals, perennials, climbers and groundcovers

All vegetables, herbs and fruits

Potted plants including vegetables, herbs, palms and indoor plants

Safe to use on new plants in the garden or in pots indoors or out - its gentle slow release formulation will not burn young leaves or roots

How to use

Easy Sprayer

  1. Shake the bottle well before attaching to the hose - ensure the thumb switch is in the OFF position first
  2. Tighten the hose connector on the handle prior to connecting the hose; turn the hose tap on
  3. Slide the thumb switch to the ON position to FERTILISE or slide to the WATER position to just water your garden
  4. Walk slowly using a sweeping action to evenly distribute the spray over the measured garden area (the bottle should empty in approximately 12 - 13 minutes
  5. When finished, switch to OFF position and turn off water

When using the Concentrate:

  1. The 1L Concentrate comes with a measuring cap that will dispense 30mL , the usual amount required for 9 litres of water
  2. The concentrate can also be used in a pump sprayer. Use the same dilution rate as for the watering can
  3. The table is a guide for using the Concentrate in specific situations:
